# MetMo's Brass Gear Train: An Engineering Marvel as Desk Toy 16,384:1 gear ratio brings physics principles to your fingertips in solid brass. - **Source:** [Yanko Design](https://brifing.si/source/41d28791-ef47-4e0b-a40a-2a5efca0c11b) - **Published:** 2026-07-14 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/9381f30e-a1dc-4c81-adc2-ccdd31befef3 ## From Kinetic Art to Engineering Inspired by Arthur Ganson's 'Beholding the Big Bang', MetMo condensed cosmic-scale gear concepts into desktop dimensions. The 16,384:1 ratio mechanism demonstrates torque multiplication through hands-on interaction. ## Time Travel Sensation While the top gear spins freely, lower gears appear nearly stationary - a visual paradox demonstrating gear reduction. Reverse the operation by turning bottom gears, and watch upper gears spin wildly out of control. ## Tactile Engineering Lesson Hand-finished brass gears manufactured to watchmaking precision. Exponentially increasing resistance at each level makes abstract torque concepts physically tangible. Most users can't manually turn beyond the 6th gear. ## Aerospace-Grade Manufacturing All components CNC-machined in UK to aviation tolerances. Stainless brass and anodized aluminum base ensure decades of flawless operation. Gear meshing rivals Swiss watch smoothness. ## Functional Design Details Anodized base optimizes center of gravity while preventing corrosion. Integrated locking pin system allows portable use. Realigning gears to reinsert pin requires perfect synchronization - a miniature planetary alignment puzzle! ## Multipurpose Marvel This object simultaneously serves as conversation starter, engineering demo, and decorative sculpture. Light-reflecting brass surfaces and mechanical aesthetics guarantee office desk appeal. ## Physics in Your Palm MetMo's design bridges education and entertainment by making complex principles interactively tangible. Its greatest achievement lies in transforming theoretical physics into an emotionally resonant tactile experience. ## Sources covering this story - https://www.yankodesign.com/2026/07/13/ever-wondered-how-gearboxes-and-torque-work-metmos-latest-edc-turns-the-physics-into-fidget-fun/?utm_source=rss&utm_medium=rss&utm_campaign=ever-wondered-how-gearboxes-and-torque-work-metmos-latest-edc-turns-the-physics-into-fidget-fun — --- _Summary written by Brifing from the original reporting.
